- Hello EveryBody,
Today I bought/used an inexpensive Euro 28
USB soundcard U-Control UCA202 Behringer.com
Unfortuality it was not sensive enought
It needs about 1 Volt eff for the line inputs
so I build on matrix pcb 2 audio pre amplifliers
with 1 transisto bc547 in each channel.
Now I had gain enough.
These circuit uses about 2 mA at 12 volt.
The fun is that I can have two SoundDoppler.exe running on
one PC with two scanners and two antenna arrays.
And this al displayed on MyMapping.exe
I found out that it is handy to have more colors arrowpoints
so I can see on the map and stationairy from wich doppler the arrow came.
So I have now a red, yellow and magenta arrows.
Red MyOwn, Yellow MyAlias and other Callsigns Magenta.
I did also work today on my New Arduino Uno board to
create a SoundDopplerGenerator with softwitching
and pre and post decay control signals for the
So the packet.tx file or df-report
should have maybe also a setting for the destination field
like APDF01 APDF02
It can ofcource also have a callsign alias with a ssid
Don't now yet how to do that in SoundDoppler.exe.
